Or,

Silence Speaks by edema_ruh for Ame_Artistry

Summary
Katsuki stares at him, taking in the sight of Izuku in his pajamas and shivering like crazy with bloodshot eyes and disheveled hair. He frowns.
He’s too smart not to immediately realize Izuku isn’t coming from his bedroom, and slowly, silently, takes in the horrible looks of him from head to toe. He’s not okay – but he didn’t come for me this time?
Dark bags under his eyes, pale face, shuddering body. A wave of deep worry hits Katsuki like a truck, and he leaves the damn breakfast behind to approach and reach for Izuku, meaning to pull him into a warm embrace like he’s often taken to doing – he looks like he needs one.
But Izuku immediately flinches away.
Alternatively: Izuku has bad nightmares about the War and doesn't know how to cope. He relies on Katsuki for comfort for a while, until one nightmare about his death makes him decide to put his distance between the two of them. As it turns out, Katsuki doesn't know how to cope with that either, and trouble only increases when Izuku accidentally hurts Katsuki during a UA training.

Summary
The instant Katsuki crossed the threshold, the world fell away—no light, no sound, just sideways through something too narrow to fit his soul. Somewhere in the marrow of him, a thread pulled tight.
A direction. A singular, aching gravity.
Izuku.
His name wasn’t a word anymore. It was a compass. A pulse. A promise embedded in every beat of his heart.
When a mission goes wrong and Izuku vanishes into the multiverse, Katsuki chases him.
In every world, one thing becomes achingly clear:
Izuku always chooses him.
Every time. Every version.
Except theirs.
And now that Katsuki’s seen versions where they get it right, one truth won’t let him go:
he wants that too.OR
They’re pro heroes.
They’ve fought villains. Saved cities.
But saying I love you?
Apparently too hard.Bookmarked by ObscureBrainwaves

Summary
"You don't get to just disappear on me!" Katsuki snarled, face inches from Izuku's. "Almost two months, Deku! Two fucking months of radio silence! I thought something happened to you, I thought—"
"If something happens to my baby, I will fucking kill you!" The words exploded out of Izuku before he could stop them.
"Kacchan!" Izuku lunged forward, grabbing his shoulders. "Breathe! Kacchan, breathe!"
Katsuki gasped, sucking in air like a drowning man. Izuku ran to the kitchen, grabbed a glass of water, shoved it into Katsuki's shaking hands.
"Drink. Slowly. That's it."
Katsuki drank, eyes still wide and unfocused. When he finally lowered the glass, his voice came out hoarse: "You're what?"
OR: UA Teacher Izuku Midoriya got pregnant. That's it, that's the plot.

Summary
Shouto wakes up in the hospital after the final battle is finally won. But at what costs? Where will his family go from here? Is Touya dead? Does he deserve to be dead? Does Shouto /want/ him to be dead? Shouto can always count on his best friend to be there for him, and he will be there in return for Izuku. After all, they’ve both been through so much.
AKA my “fixing” of the MHA ending because there were a few things I was unsatisfied with. Featuring the Todoroki siblings and Izuku processing all that went down, sibling bonding, and a happier ending for Touya bc I refuse to let him suffer to death in a tube.
